Switching output connection diagram SWIO_1 / SWIO_2
Attention!
Each configured switching output is short-circuit proof! Do not load the respective switching
output of the BCL 504
i
with more than 60mA at +10 … +30VDC in normal operation!
Notice!
Both switching inputs/outputs SWIO_1 and SWIO_2 are configured by default in such a way
that they function as
switching inputs
:
• Switching input
SWIO_1
activates the
start reading gate
function
• Switching input
SWIO_2
activates the
reference code teach-in
function
The functions of the individual switching inputs/outputs are programmed via the display or
via configuration in the
webConfig
tool under the Switching input or Switching output
heading.
For further information, see also "Commissioning and configuration" on page 100.
